Question

How is rain formed

How is acid rain formed

Aim

My aim was to find out form of acid rain will affect the plants.

Hypothesis

My hypothesis was that the bleach and chemical experiment will destroy the plant because if bleach herms our skin it will defiantly destroy the plant.

I also think that tap water will come first because their more us to it.

Independent Variables

Position (on the bench)

Lighting (in room before taken to school)

Temperature (of the room before taken to school)

The angle of which the spray was taken.

Dependent variables:Growth

Materials

An ice cream container (each=5)

A spray bottle (each=5)

A plant (each=5)

A bench

Method

get a spray bottle

Fill the bottle with your liquid

Get your plant

Spray your plant at 3:00pm

Take a picture and repeat for a week

How Is Acid Rain Formed

rain is formed when water from the sea evaporates and air particles rise up this is called transpiration which forms condensation which form condensation clouds perspratoin when it rains it’s called precipitation

Results

Coca cola was 1st

Lemon was 2nd

control was 3 ( tape water)

Laundry detergent was 4th

Detergent was 5th

My plant graph

Research

Nox +ho2= NITRIC ACID

So2+ H20=sulfuric acid

Conclusion

My hypothesis was half right. The Chemicals experiment did come last but I was surprised about the tap water experiment .

Application

I think this will have an positive influents on locals the are incrested in plant grow but don’t have an professional advise to.

It will also help people to kwon what not to do near plant.
